When doing any stitch other than a tent stitch, the kinks in the ribbon must be removed. There are several ways to do this, one of which should be right for you. The easiest way is to wet the working length of the ribbon. Use a damp sponge, white paper towel, cloth or whatever, running the Neon Rays through. It is best to use water, as opposed to any other liquid, to remove the kinks. Let the Neon Rays dry before stitching. Another method is to pop Neon Rays as you would Rozashi Silk. Wrap it around a finger on each hand and snap it. The problem with this is that it will thin your length of fiber. If this is not a concern, go ahead. If it is, use a different method. Two other methods are steaming or ironing. That seems to be too much effort for most people. A clean, hot light bulb is a handy substitute. You must lay Neon Rays or you will lose the beauty of this yarn.
A laying tool is needed and there are several different ones on the market, all of which work well. Also, note that stitching tension will have an effect on the coverage of Neon Rays. A tighter tension will thin this yarn out and a looser tension will allow it to expand on the canvas. Also, try stabbing Neon Rays with the needle after it is threaded. By piercing the ribbon with the needle, you will avoid it slipping out of the needle. This will help you control your tension. Bury the Neon Rays well when you begin and end, as it will slip out easily. A Bargello tuck is recommended. (14-18 count canvas, long stitches on 18-22 count)
